IPhone XS mobile phone touch failure repair

IMG_256
The touch of iPhone XS phone failed. After measurement, it was found that there was a line with a resistance value of OL, that is, the line was disconnected. Because the line is connected to the middle layer, the motherboard can only be layered. After layering, the disconnected line can be repaired, and then attached back to the motherboard for fault repair.

Separate the motherboard, check the solder joints of the motherboard to see if there are obvious virtual solder joints, and then measure the solder joints from the motherboard to the upper layer. It is found that the main board has obvious solder joints falling off. After the solder joint is repaired, the measured resistance is normal. Re-attach the upper and lower layers, and repair the fault.
